I do a variety of things like index cards, saving magazine tear outs in a folder, tagging recipes on Google Reader, Pinterest, but I think I'm going to migrate everything to Zip List. I've been using it for a few months now and I can input all my recipes on there so I can access them from the grocery store. It's easy to search and it will create shopping lists for you with one click. So efficient!

How do you keep those recipes not from cook books organized? Do you use apps like Zip List?
